|578923 is a borb created from some recordings of static on my own shortwave radio, paired with clips taken from the absolutely fascinating Conet Project.|
The Conet Project: Recordings of Shortwave Numbers Stations is a four-CD set of recordings of numbers stations, mysterious shortwave radio stations of uncertain origin believed to be operated by government agencies to communicate with spies "in the field". The collection was released by England's Irdial-Discs record label in 1997, based on the work of number station enthusiast Akin Fernandez. 
The Conet Project has since become somewhat of a cult sensation and counts many musicians and filmmakers among its fans, including Wilco frontman Jeff Tweedy, Boards of Canada, former Faith No More vocalist Mike Patton, and director Cameron Crowe. Samples from the collection have been used in numerous films and albums, including Crowe's film Vanilla Sky and Wilco's Yankee Hotel Foxtrot album, the latter of which was an issue of legal dispute; Jeff Tweedy did not seek permission to use the Conet sample and Irdial sued for copyright infringement. The incident sparked debate about who exactly owns copyright concerning recordings of numbers station transmissions, but Tweedy ultimately decided to avoid taking the matter to court, agreeing to pay Irdial royalties and reimburse its legal fees. 
In keeping with the 'Free Music Philosophy', the label has made the entire collection available for download in MP3 form (along with a PDF version of the included booklet) on its website completely free of charge and encourages fans to freely distribute it on file sharing networks.
